ELECTRIC-MOTOR WHEEL.

SPECIFICATION forming part of Letters Patent No. 660,217, dated October23, 1906;

Application filed December 13, 1899. .5e1'1al No. 740,202. (No model.)

T0 at whom it may concern;

Be it known that I, CHARLES E. IsBILLs, a citizen of the United Statesof America, and a resident of Passaic, in the county of Passaic andState of New Jersey, have invented certain new and useful Improvementsin Electric-Motor Wheels, of which the following is a specification.

My present invention relates to the mechanical construction of a wheelgenerally intended for a vehicle or car, but particularly adapted foruse on an automobile, the wheel being so constructed that the motor iswithin the wheel. The tire of the wheel is slipped upon the field-magnetring and held between dished webs, which are secured to themagnet--1'ing, with their circumferential edges projecting for holdingthe tire and their central portions being formed with bearings for theaxle of the automobile, the armature of the motor being fixed to saidaxle. Handholes are out in one of the webs and are provided withremovable covers, the commutator and brushes being within reach of thehandholes within the webs and located between the armature of one of thewebs, the collector-rings being located between the armature and theother Web and serving to communicate the current from the fixed portionsof the automobile to the revolving field-magnets.

All the details of the invention are described by reference to theaccompanying drawings.

Figure 1 is a vertical section of the electric-motor wheel, some of thesmaller circular parts not being sectioned. Fig. 2 is an outsideelevation of thewhole wheel looking perpendicularly toward the axle.Fig. 3 is a side elevation of that web which is provided withliandholes. Fig. 3 is a front view of one of the covers for thehandholes, both being alike. Fig. 4 is a'vertical section of the twowebs removed from the rest of the wheel, but placed in the same relativeposition to each other. Fig. 5 is a side elevation of the other dishedweb. Fig. (5 is a vertical elevation, partly in section, of thefield-magnet ring looking perpendicularly to the axis. Fig. 7 is a sideelevation of the same ring. Fig. 7 is a portion of the ring broken outwith the core shown in section.

A is the tire, mounted upon the field-magnet ring B, having thepole-pieces or cores C, which, as in any motor, maybe of the desirednumber, as my invention has nothing to do with the number offield-magnet poles.

D is a web with rounded surfaces, conveniently termed a dished web,secured by screws E to the magnet-ring B and having its circumferentialportion projecting beyond the ring B, while F is a similar web on theother side of the ring B, having its edge also projecting, so that thetire A is held by the projecting edges upon the ring B in an elfectivemanner. The web D is made in halves and is formed with half a bearing Gand H upon each half. The bolts E while holding the halves to the ring Bat the same time hold the halves to form one whole. The bearings G and Hproject outward from the wheel and surround the axle I. There arehandholes J out through the web. These may be covered up by means ofcovers K. (Shown in Fig. 3.) There are two other holes L in the same webfor holding brush-holders, one of which is shown at M. There is abearing N formed centrally upon the web F and extending into the wheel,considered as a whole, and said web is fastened by screws E to the ring13. At the inner end of the bearing made of the halves G and H the shaftis made smaller to receive the commutator 0, whose details are the sameas in commutators generally. Justbeyond the commutator the shaftis madesmaller yet to receive the washer P. Next to the washer is the armatureQ, bearing against said washer. Just beyond the armature Q the axle ismade smaller to receive the collector brush-holder R, whose centralportion is screwed upon the axle against the armature Q. The axle I ismade smaller beyond the central portion of the brush-holder, andsurrounding this last and smaller portion is the bearing N, and,finally, nuts S hold the bearing upon the axle. Of course bushings ofany suitable kind should be inserted between the axle I on the one handand the bearings G, H, and N on the other hand.

The operation of the device consists simply of the same kind as takesplace in other motors, the novelty being in the construction and not inany new mode of operation. The

' armature being fixed to the axle, the electric energy causes thefield-magnet to rotate, which, being a wheel, causes the vehicle totravel.

The Webs completely inclose all the elements of the electric motorsuchas the armature, field-magnet coils, commutator, collector, andbrush-holdersin a perfectly dustproof manner.

I do not claim, broadly, an electric-motor wheel for vehicles; but

I claim as my invention 1. In an electric-motor wheel, the combina tionwith the tire, of a field-magnet ring, webs extending in asingle piecebeyond said ring, a tire surrounding said ring and located between theextensions of said webs, an axle, and bearings formed respectivelyin asingle piece with said webs and surrounding said axle.

2. A11 electric-motor wheel consisting of the combination of afield-magnet ring having internally-radiating cores and a circularcontour, a tire mounted at the circumference upon said ring, webs havingcentral bearings respectively formed thereon, secured to said ring andprojecting beyond the same for the purposes described of holding saidtire upon said ring, and an axle having the armature and commutator ofthe motor fixed thereon,

brush-holders for the commutator carried upon one of the webs, andcollector-rings mounted upon the bearing of the other web, and abrush-holder for the collector-rings screwed upon said axle against saidarmature.

3. In an electric-motor wheel, the combination with a field-magnet ring,a dished web fastened to said ring on one side and having a bearingformed in a single piece with said web and extending away from thearmature of said motor, a commutator on the axle of the motor betweensaid bearing and said armature, a second dished web secured to the otherside of said ring and having a bearing formed in a single piece withsaid web and extending toward said armature, and carryingcollector-rings, suitable brushes being provided for said commutator andsaid rings, and the field-magnet, armature, commutator, collector andbrushes being completely inclosed in a dust-proof manner within saidwebs.

In testimony whereof I have hereunto subscribed my name this 9th day ofDecember,
